WILLIAM S. COOPER, OF PHILADELPHIA, PENNSYLVANIA.

OVERFLOW VALVE FOR WASH-BASINS.

SPECIFICATION forming part of Letters Patent No. 267,156, dated November 7, 1882,

Application filed September 17, 1881. (No model.)

To all whom it may concern Be it known that I, WILLIAM S. COOPER, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Overflow-VaIves for \Vash- Basins, of which the following is a specification.

My invention relates to improvements in mechanism for maintaining a proper supply of water in a wash-basin without the aid of the usual detachableplug, preventing the overflow of water from the basin, and promptly disposing of the waste water. These objects I attain in the manner which I will now proceed. to describe, reference being bad to the accompanying drawings, in Which Figure 1, Sheet 1, is a vertical section of a wash-basin with my improved waste and overflow device; Fig. 2, a sectional plan on the line 1 2; Fig. 3, a sectional plan on the line 3 4; Fig. 4, Sheet 2, a view of part of Fig. 1; and Fig. 5, a vertical section on the line 5 6, Fig. 4. Fig.1 is drawn to a smaller scale than the remaining figures.

A is the wash-basin, and B the top of the wash-stand, to the under side of which the basin is attached in any suitable manner.

To the outlet-branch a of the basin is secured the upturned end of the waste-pipe D, which communicates with the compartment 6 of the overflow-chest E, the latter having a second compartment, f, communicating with the first at i, and both communicating with the outlet m of a casing, F, which is secured to the bottom of the chest E, a suitable packing intervening between the two. The chest E has at the top a tubular extensiomp, which is threaded externally and passes through the top B of the stand, and is secured thereto below bya nut,q, and above by the internallythreaded flange t of a. cap, H.

A-valve, I, attached to the lower end of the valve-spindle J, is adapted to a seat, 20, in the bottom of the compartmente of the overflow-chest, this seat being formed by the packing between the said chest E and the casing F below the same.

To the upper end of the rod is attached a rack, K, forming partof a quadrangular frame, K, which is contained within and guided by the cap H.

A spindle, M, provided with a suitable handle, N, projects transversely into the cap H, and has one bearing in an internal projection, s, in the cap and the other in a stuffing-box, u,

the spindle being provided with a pinion, l,

which gears into the abovementioned rack.

The valve-spindle J is guided at a short distance above the valve by rods .r m, driven through holes in the spindle and extending nearly across the compartment 0 of the overflow-chest.

When the valve[ has been raised the water will pass from the basin through the outlet a, pipe D, and outlet m, and through the wastepipecommunicating with the latter; butshould the valve be closed and water allowed to flow into the basin it cannot reach a higher level therein than that determined by the position of the communication t between the two con1- partments of the overflowchest.

The usual detachable plug fitted to the outlet of an ordinary wash-basin is dispensed with, as the closing of the valve insures the introduction of a proper supply of water into the basin, from which the water cannot overflow, owing to the freedom of thedischarge therefrom, due to thelarge area or the opening 2' and of the portionfof the overflow-chest.

The handle N is such that when the valve is raised said handle occupies an inclined position on one side of a vertical line drawn through the centerot' the spindle M, and when the valve is depressed the hand e occupies an inclined position on theopposite side of said line, so that the handle tends to maintain the valve and valve-rod in either of the positions named after the adjustment has been eifected.

I claim as my invention- The combination of the overii iw-chest, the valve I, and valve-spindle J, with rack K, the cap H, the pinion l, the spindle M, and the handle N, adapted to hold the valve-rod in either of its extreme positions, as set forth.

In testimony whereof I have signed my name to this specification in the presence of twosubscribing witnesses.

WILLIAM S. COOPER.
